Threaded to the 3-48 UNC standard, it features a 5\/64-inch hex drive and a 5\/8-inch length under head. The screw is fully threaded along its entire length, maximizing thread engagement across thin materials or close-clearance joints. Constructed from alloy steel with a black oxide finish, it delivers solid tensile strength with moderate corrosion resistance. This fastener is installed by machinists, maintenance technicians, and assemblers working on mechanical equipment, fixtures, and precision assemblies.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in light mechanical assemblies, instrument housings, fixtures, and equipment where a low-profile socket drive is preferred over slotted or Phillips heads. The 3-48 UNC thread pitch is common in precision hardware, small-bore machine components, and instrumentation. The black oxide finish provides a clean, consistent appearance and mild resistance to oxidation in dry or lightly controlled environments. Sold in a minimum order quantity of 100 pieces, making it appropriate for production or maintenance stock.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-48 UNC thread form for standard precision fastening applications\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch length under head with full threading for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003e5\/64-inch hex socket drive for use with standard hex keys or Allen drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for high tensile strength in compact fastener form\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating provides mild corrosion resistance and uniform dark finish\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM A574 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 3-48 UNC hex socket cap screw suitable for threaded holes conforming to ASME\/ANSI B18.3 specifications in light mechanical assemblies, precision instruments, and fixtures.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed using a 5\/64-inch hex key or Allen-drive tool. Verify the mating threaded hole is clean, properly tapped to 3-48 UNC, and free of debris before driving the fastener. Do not exceed the rated drive engagement or apply impact tools to this fastener size, as small-diameter alloy cap screws are susceptible to shear at the drive socket. Follow applicable torque guidelines from ASME B18.3 or the equipment manufacturer for this thread class.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3-48 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 5\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3 and ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 581081PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51710011146546,"sku":"581081PR","price":4554.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/93e3c9bb9da9740367669e0984586aad.jpg?v=1788463146","url":"https:\/\/voomisupply.com\/products\/value-collection-581081pr-hex-socket-cap-screw-3-48-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
